A day or so after in installed ubuntu mate, the right click and it’s menu won’t appear… and I can’t copy any text either
After making sure mouse preferences isn’t set left-handed (this reverses the buttons) do you still have the install media to boot into a live session (the “Try” selection)? Is it ok there? Which version?
i have ubuntu mate 17.10 and i have it installed on my laptop
Menu System -> Preferences -> Hardware -> Mouse
Is Mouse Orientation set Right-handed?
17.10 is in Alpha 2 testing, it may not be free of problems.
